GMNavDisc.com says it's for the 2007-2010 Escalade but not 11-12. For 11-12 it says 22917273 is the newest disc. Would you know why? I'm asking because I know someone with a 2011 Esky who needs the newest disc.
It says that part number is for:
2008-2012 Buick Enclave
2006-2011 Buick Lucerne
2007-2010 Cadillac Escalade
2007-2009 Chevrolet Equinox
2007-2012 Chevrolet Traverse
2007-2012 GMC Acadia
2007-2009 Pontiac Torrent
2007-2009 Saturn Outlook
2007-2009 Saturn Vue
